建立了由铜绿假单胞菌、荧光假单胞菌和肺炎克雷伯菌组成的生物膜模型，研究了结构异质性与流体动力学的关系。采用激光共聚焦扫描显微镜非侵入性粒子图像测速技术测量了生物膜系统中的局部流体速度。在有无生物膜的情况下，测量了管式和多孔介质反应器中的速度分布。在生物膜通道内观察到液体流动；生物膜的同时成像允许液体速度与生物膜的物理结构有关。
A model biofilm consisting of Pseudomonas aeruginosa, Pseudomonas fluorescens, and Klebsiella pneumoniae was developed to study the relationships between structural heterogeneity and hydrodynamics. Local fluid velocity in the biofilm system was measured by a noninvasive method of particle image velocimetry, using confocal scanning laser microscopy. Velocity profiles were measured in conduit and porous medium reactors in the presence and absence of biofilm. Liquid flow was observed within biofilm channels; simultaneous imaging of the biofilm allowed the liquid velocity to be related to the physical structure of the biofilm.
